COW-TAIL HOLDER.

Specication of Letters Patent.

' Patented Oct. 17, 1911.

Application led April 10, 1909. .f Serial No. 489,151.

To all whom 'it may concern.'

Be it known that I, HERMAN C. MALM- sTRoxI, a citizen of the United States, residing at Hallock, in the county of Kittson and State 'of Minnesota, have invented certain new and useful Improvements in Cow-Tail Holders, of which the following is a specilication.

-My invention relates to improvements in devices for securing the free end of a cows tail to her leg to hold the taill from interfering with the operation of milking.

To this end my invention consists in the features of construction, combination and arrangement of parts hereinafter particularly described and claimed. f1

In the-accompanying drawings forming part of this specification, Figure 1 shows-my invention in use; Fig. 2 is a plan View of the invention; Fig. 3 is a section on line -m of Fig. 2, and Fig. 4 is a section on line ,'1/-3/ of Fig. 3.

' In the drawings A represents the casing of the device within one end of which the curved jaws 2 and 2a have pivotal supports 3. Slidable between the inner power arms 4 of the jaws 2 is the tapered spreader 5, the spreader being formed with a finger piece 6 extending outwardly through a slot 7 in one side wall of the casing. A coil spring 8 surrounds the stem 9 of the spreader and normally holds the spreader forced inwardly to separate the inner ends of the jaw and hold the outer ends of the jaw in the closed position shown in Fig. 2. The spreader acts against the tension ofy the strap spring 10 which is secured at one end 11 to the adjacent side wall of the casing an'd bears at its free end against the side of the power arm of the jaw member 2 as indicated in Fig. 2. In order to turn the jaw 2a with the jaw 2 I form the jaw 2 with a bearingI projection 12 fitting into a. recess 13 in the jaw 2'al intermediate of the pivots 3. The opposite end of the device is formed with a hook portion 14inside nf which jaw member 15 upon its fulcrurn to carryl has pivotal support 16. The free end of the jaw l5 has sliding link connection 17 with the inner end of the lever arm 18. The lever 18 has fulcrum support 19 in the casing and is formed at its free end with a finger hold 20.

In use, the withdrawing of the spreader against the tension of its spring 8 will allow the jaws 2 and 2to be turned upon their pivots 3 into open position under the pressure of the spring 10. This allows the jaws to be slipped over the tendon 21 of the cows leg, as indicated in Fig. 4. The spreader then being released -w1ll be carried into spreading position under the. inuence of the spring 8, `carrying the jaws 2 and 2 y upon their supporting pivots 3 into the gripping position shown in Fig. 2. The free end of the cowfs tail may be secured in the oppositeend of th` device by turning the arm 18 into the position shown in Fig.

4, carrying the jaw 15 inwardly away from the hook 14, the free end of the cows tail then being inserted between the hook 14 and jaw 15, the actuating lever being turned the hook 14 into gripping position with e lever 18 acting as a cam, as shown in Fig. 2.

I claim as my invention:

In a device of the class described' carryin upon one end a pair of pivotally supporte jaws, a bearing upon the inner side of one jaw .fitting into a recess in the 'other jaw, a. strap spring bearing against the outer side. of one of said jaws for turning them upon their pivots through the medium of said bearing, gripping means carried by the other end of said device, and an actuating lever for said gripping means.

In testimony whereof I afiiX my signature in presence of two witnesses.

HERMAN o. MALMSTROM.
